My invention relates to internal combustion engines, and more particularly to the construction and arrangement of the manifold devices, both for the intake and the exhaust, employed in connection therewith'.

lin the present day gas engine practice, due to incompletely gasifying the liquid fuel and the consequent incomplete combustion, diiiculties have been experienced with carbon deposits in the explosion chambers, im-

perfect lubrication in the cylinders, and

.smoke in the exhaust.- The object of my present invention is to overcome these diiliculties, and in carrying out thesame in order to completely gaslfy the liquid fuel, l utilize the heat in the exhaust gases by completely inclosing the intake manifold in the exhaust manifold, and it has been found by actual use of the apparatus hereinafter 'A described, that the fuel is so heated as to be cracked or transformed into a fixed gas at a temperature approximating 1000 li., the transformation being effected irrespective of whether high or low grade fuels are employed, and the same is the case, even when the fuel contains a certain percentage of As will be readily appreciated by feeding a fixed perfectly dry and absolute gas to the engine cylinders the combustion of the same when compressed and fired, is

substantially complete and therefore overcomes the trouble with carbon deposits in the combustion chambers, with lubricating the cylinders, and also with smoke in the exhaust. The manifold structure made in accordance with my invention will be hereinafter more particularly described, in conjunction with the accompanying drawing, which is a diagrammatic sectional elevation illustrating the same.

Referring to the drawing, the cylinders of the gas engine are illustrated respectively at A, B, C, and D, and are constructed in pairs as commonly done at the present time. The fuel inlet to the cylinders A'and B is indicated at 10, and the fuel inlet to the cylinders C and D at 11, the exhaust from the cylinder A at 12, the exhaust from the cylinder VB at 13, the exhaust from the cylinder C at 14, and the exhaust from the cylinder D at 15.

The intake manifold is indicated at 10, and as is customary, is provided with branches 17 and 18 leading respectively to the intake 10 of the cylinders A, B, and the inlet 1]. of the cylinders C, D. rlhe top wall 161 of the manifold is straight and relatively at and hence acts to spread or divide the fuel and thus facilitate the heating thereof. The intake manifold also includes a downward extension 19 at the extremityof which aA carbureter 20 is suitably attached, the carbureter being provided with a pipe 21 supplyin the'same with liquid fuel from any suita le source of supply. l also employ an exhaust manifold 22, which completely surrounds or incloses the intake manifold 16. The exhaust manifold 22 is also provided with branches 23 and V24 reiti spectively, the former surrounding the' .branch 17' of the intake manifold and extending suciently far to embrace the exhaust port 412 of the cylinder A, while the branch 24 surrounds the branch 18 of the intake manifold and extends sufficiently far to embrace the exhaust port 15 of the cyl- `inder D. It will be noted that when in their assembled positions, the top of the intake manifold 16 is immediately beneath the exi haust ports 13 and 14- of the cylinders B and C. lThe exhaust manifold also includes vthe downward extension `25 inclosing the extension 19 of the intake manifold which passes through an opening provided therefor adjacent the extremity of the extension 25, so that the carbureter may be 'connected exteriorly of the exhaust manifold. The aperture in the exhaust manifold through which the extension 19 passes, is substantially at the end of the extension 25 so that 1. .1g From the foregoing description it will be apparent that the entire heat of the exhaust before the same reaches the 4engine cylin-` 10.

ders for usel therein in driving the engine and the fuel supplied the cylinders is only ,a

dry fixed gas, unmixed with any of the liquid fuel, vthe combustion in the engine is i v ract'ically complete and results in no caronV deposits, making it possible to perfectly lubricate the engine pistons and also obviates any, smoke in the exhaust gases.

I claim as-my invention: i 1,. The combination of an internal combustion engine, a carburetor; and a heat transformer, the heat transformer being so ,constructed as to raise the temperature of ithe carbureted air to the cracking point.

, which is accomplished at approximately a f 2. The combination of an internal combustion engine, a carburetor, and a heat utransformer, theheat transformer being so 'constructed as to raise the tem erature of the carbureted air to the crac g point,

temperature of 1000 degrees Fahrenheit.

3.In an internal combustion engine and in combination with the cylinders thereof,

la carburetor; a heater vfor the mixture vproduced in said carburetor, said heater consisting of an elongated chamber communicating with the carbureter and inclosed within the exhaust compartment and means to discharge the exhaust gases from the engine into said comlpartment at .a plurality of ports distribute along the chamber.

4. In an internalv combustion' engine and in combination with the cylinders thereof, an intake manifold .having branches connected to the inlet ports of the cylinders and 'a downward extension, an exhaust manifold having branches surrounding the said branches of the intake manifold and embracing the discharge. ports of the said cylinders and also a downward extension surrounding the downward extension ofthe intake manifold and terminating in a discharge adjacent the inlet to the downward extension of the intake manifold, a carbureter connected to the extension of the intake manifold exteriorly ofthe extension vof the exhaust manifold, a fuel feed pipe for the carbureter, a hot air chamber in the upper portion of the exhaust manifold, and a connection between the hot a'ir chamber and the inl'et side of the. carbureter.
